Construction and Spatial Logic The scope and sequence of this program is phenomenal. Using just eighteen blocks, your children will experiment with construction, geometry, logical analysis, perspective, design, and spatial logic. Each spiral-bound book is systematic in its presentation, with multiple levels and escalating complexities. Spatial proficiencies are vital for everyone, but today's sedentary children often lack a natural way to develop this ability. These three books and set of blocks provide an enjoyable and successful approach to making sure your children acquire these essential skills.

Equilibrio: It Starts with Fine Motor Skills The Canadian Toy Testing Council awarded Equilibrio their 2006 Best Bet Award, and for good reason. Using eighteen sturdy, precisely cut, solid plastic blocks, your children build the structures illustrated. Each successive structure is more complex to build and more difficult to balance, requiring the use of fine motor skills, creativity, and perseverance. As an educational bonus, while accomplishing these tasks children will subconsciously be experimenting with basic concepts of geometry and balance. While the beginning pages may be easy enough for a four-year-old, the more difficult pages will challenge any adult. This is the beginning set in the series. For ages four and up.

Architecto: Translate 2-D into 3-D In this volume, your child utilizes the same blocks used with Equilibrio to construct one of fifty illustrated three-dimensional structures. For each model, the type and number of blocks required are indicated at the bottom of the page. There are six levels of difficulty, and your child will find that the most grueling level requires fairly advanced logical analysis and spatial perception. Thankfully, answers are included. For ages six and up.

Cliko: Perspective, Depth, and Geometric Forms This is the most challenging book in the series. Given an illustration that mimics what you would see through a camera's viewfinder and the type and number of blocks required, your child will be asked to construct a three-dimensional structure that conforms to the image. As he works through the exercises and the illustrations become exceedingly difficult, your child will be given additional views of the illustration for help and clarity. Answers are included for the faint of heart, but participants are encouraged instead to develop perseverance with the goal of increasing these necessary skills. If this doesn't give your child a profound understanding of perspective, depth, and geometric forms, then I don't know what will. For ages six and up.
